Australia’s only operational storage project and a world class research facility, that has safely stored 65,000 t of CO2 as part of Otway 1, and attracting wide community interest and support CO2CRC Otway 2 is now underwaycommunity interest and support. CO2CRC Otway 2 is now underway

What has CO2CRC Stage 1 achieved?
• Demonstrated safe and effective storage of 65000 tonnes of CO2 in a depleted gas field with no leaks
• Confident that would detect CO2 migration into the overlying formation and a significant leak into the atmosphere or soil
• The reservoir models gave good predictions of “break through” of CO2g g p g
• Have been able to sample ‘in situ’ formation waters from 2 km depth.
• Provides insights into the potential for CO2 enhanced gas recovery
• The community has remained supportive and interested
• The regulators are happy
• Set the scene for Stage 2
What have we learned from CO2CRC Stage 1?• Essential to take the regulator along with you, as the project is developed and
implemented, particularly in the absence of clear regulations
• CCS R&D or pilot projects should not be regulated under the same regime as a commercial-scale project – potentially too onerous and too expensive
• Getting the right arrangements in place for handling liability is crucial to the development of the appropriate company structure – and vis versa
• Assume it will cost you more than the estimates suggest – we worked with a 20%Assume it will cost you more than the estimates suggest we worked with a 20% contingency and used all of that
• You are unlikely to achieve the Sleipner “gold standard” of seismic imaging onshore and we have to be realistic about using onshore 3D seismicg
• Onshore 3D seismic surveys are disruptive to landowners and we will need effective fixed seismic arrays for onshore monitoring
• Tracers are very valuable in a research environment but are not appropriate for• Tracers are very valuable in a research environment but are not appropriate for ongoing use in large scale CCS projects because of the problems of contamination
• Effective relations can be built up with the local community, but start very early, be completely open and still expect at least one difficult person!completely open – and still expect at least one difficult person!
